IMPROVED COMPOSITION TOR FIRING- AND CARBONIZING IRON.

ground together, as a means for refining iron, and converting iron ,intosteel.

In'smelting the crude ore, I prefer to use unslaked lime with the fuel,say about one half as much lime asfuel.

I In resmelting and puddling from iron not first treated by my process,I' also prefer to use lime as above, the efl'eet of using the lime beingto remove the sulphur and slag. v

But as an eficient (or further) refining-process, I use,

in the erueibles, peat and manganeseground together, in the proportionof about nine pounds of peat, and from one to two pounds of manganese,to ahundred pounds of iron, and I aiterward treat the iron by hammeringand rolling as usual.

I do not claim the use of lime in smelting iron; nor do I claim the useof peat alone, in the treatment of iron, nor the use of manganese alone;but I clainn'in the earboniz'at-ion of iron, to refine or convert itinto steel, the employment ofpeat and n1anganese, substantially as andin the proportions specified.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
